2(3x-4)3x=1
We move all terms to the left:
2(3x-4)3x-(1)=0
We multiply parentheses
18x^2-24x-1=0
a = 18; b = -24; c = -1;
Δ = b2-4ac
Δ = -242-4·18·(-1)
Δ = 648
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{648}=\sqrt{324*2}=\sqrt{324}*\sqrt{2}=18\sqrt{2}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-18\sqrt{2}}{2*18}=\frac{24-18\sqrt{2}}{36} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+18\sqrt{2}}{2*18}=\frac{24+18\sqrt{2}}{36} $
